I am using ArcGIS for Server 10.2.2. My WebMaps were created using ArcGIS Web AppBuilder Developer Edition 2.4.
The WebMaps work good in these browsers: Internet Explorer 10, Microsoft Edge, Google Chrome, and Firefox.
But, when opened in IE II, I get an "Access Denied", I mean the WebMap opens, but just spins and spins and nothing happens, essentially it is frozen stuck in some sort of app open infinite loop.
See attached for the error I get when I pull up the IE 11 console.
